SPECIFICATION forming part of Letters Patent N 0. 534,292, datedFebruary 19, 1895. Application filed October 25, 1894. Serial No.526,929. (No model.)

.To all whom it may concern.

Be it known that I, PLIN O. SOUTHWICK, a citizen of the United States,residing at Sandwich, in the county of De Kalb and State of Illinois,have invented certain new and useful Improvements in Baling-Presses; andI do declare the following to be a full, clear, and ex act descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and

to the letters of reference marked thereon, which form a part of thisspecification.

My invention relates to hay baling presses in which a plungerreciprocates within a chambered body having a lateral feed opening intowhich the hay is forced by a pair of swinging feeding plates.

The object of the invention is to provide means for throwing the feedingplates out of action at the will of the operator for the purpose ofenabling him to more conveniently insert within the feed opening thefollowers used to separate the bales.

The invention is especially adapted to the press forming the subject ofmy application for Letters Patent, Serial No. 51,261, filed June 11,1894., in which the feeding plates are actuated by means of a sprocketchain to which a reciprocating motion is communicated by means of apitman and consistsof a special form of pitman adapted to be connectedwith or disconnected from the chain at pleasure, and more particularlyto a stud and notch connection between the chain and pitman, and a leverfor lifting the pitman from the stud.

The invention consists also in such further details of construction asare hereinafter described.

In the accompanying drawings, Figure 1, is a side elevation of a balingpress to which the invention is applied, the feeding plates being inconnection with the driving mechanism. Fig. 2, is a plan view of thesame. Fig. 3, is a side elevation, the connection between the feedingplates and the driving mechanism being broken. Fig. 4, is a longitudinalvertical section of the press. Fig. 5,

is a detail on the line 5-5 of Fig. 2. Fig. 6, is a detail of the pitmanfor driving the feeding plates.

The chambered body of the press is shown at A, its feed opening beingflanked by the wings a, a. The plungeris represented at B, 55 its pitmanat b, and the elliptic gears for driving the plunger at G, D,power beingapplied to the gears by the wheel E,and its pinion F, the latter beingcarried by the shaftf, upon which is mounted the belt pulley G, which isdriven from the source of power.

The feeding plates are shown at H, H, and are mounted upon shaftsjournaled across the body A, and carrying sprocket Wheels L, L, whichare driven in opposite directions by a sprocket chain It, returning'overan idler K. A slide bar 0, is carried by and adapted to reciprocate inguide loops 0', 0', attached to the side of the body A, and isimmediately below and parallel with the lower turn of the chain is, andto which it is permanently attached.

A crank arm m, is carried by the shaft 0, of the elliptic gear 0, and isconnected with the slide bar 0, by means of a pitman M, which detachablyengages a stud Q, carried by the slide bar.

The attachment between the pitman M,'and the stud Q, is by means of aloop m, forming the outer end of the pitman and serving as a slidingbearing for the stud and having, preferably at its inner end, a recessat its upper side adapted to receive the stud so as to lock the pitmanand slide bar'together.

A crank arm S, carried by a rock shaft 8, 8 journaled in the sills a, ofthe body A, bears against the under side of the loop m. A crank arm S,carried by the rock shaft 8, and projecting oppositely from the arm S,is connected with a vertical thrust rod T, sliding in a guide loop t,secured to the side of the body A, and having a head t, adapted toreceive the foot of the operator. Down ward pressure upon the rod T,throws the crank arm S, upwardly and lifts the pitman M, so as to dis- 95 engage the recess of the loop m, from the stud Q. The pitman nowslides freely upon-the stud, the sprocket chain. The wheels and thefeeding plates remain stationary. The recess of the loop m, being at itsinner end the ICO stud Q, will be pushed to the limit of the forwardthrust of the pitman, thereby throwing back the feeding plates andleaving them in that position as the pitman recedes. The

length of the loop m, is equal to the stroke of the pitman, so that theplates are not again moved until the crank arm S, is lowered and thepitrnan falls when the recess of the loop reaches the stud, bringing theparts again in to engagement. The follower r, is introduced into thechamber of the body while the plates H, H, are stationary without dangerto the operator and is pushed up to the hay R, already compressed.

The rock shaft 8, may be provided with a crank arm S, at each end, asshown in Fig. 2, so that there may be a thrust rod 1, upon each side ofthe body A.

I claim as my invention- 1. In a baling press the combination with achambered body A, having a feed opening, of a pair of feeding platesadapted to oscillate in and out of the feed opening, sprocket wheelsmounted with the plates, a sprocket chain for driving the wheels inopposite directions, a stud in fixed connection with the chain, areciprocating pitman, a loop forming an extension of the pitman andadapted to inclose and slide upon the stud and having a recess at itsinner end for engaging the stud, and means for disengaging the stud fromthe recess.

2. In a baling press the combination with a chambered body having a feedopening and a plunger adapted to reciprocate within the body across thefeed opening, of feeding plates adapted to swing into the body throughthe feed opening between the strokes of the plunger, means for actuatingthe plunger and feed plates from a common source of power and means forthrowing the plates out of action at the will of the operator.

3. In a baling press the combination with a chambered body having alateral feed opening, of feed plates mounted at the sides of the feedopening and adapted to swing in and out of the same, sprocket wheelsmounted with the plates, a chain for driving the wheels in oppositedirections, and a reciprocating pitman in detachable engagementwith thechain.

4. In a baling press the combination with a chambered body having alateral feed opening, of feed plates mounted at the sides of the feedopening and adapted to swing in and out of the same, sprocket wheelsmounted with the plates, a chain for driving the wheels in oppositedirection, a stud connected with the chain, a reciprocating pitmanhaving a notch or lateral recess for engaging the stud, and means fordisengaging the notch from the stud.

5. In a baling press the combination with a chambered body having alateral feed opening, of feed plates mounted at the sides of the feedopening and adapted to swing in and out of the same, sprocket wheelsmounted with.

the plates, a chain for driving the wheels in opposite direction, a studconnected with the chain, a reciprocating pitman having a notch orlateral recess for engaging the stud, a swinging lever adapted to bebrought into sliding contact with the pitman whereby it may be elevatedand disengaged from the stud, and means for swinging the lever.

6.
